The Functions of Oil Demister
Oil-free compressors deliver compressed air completely free of oil aerosols, a critical requirement for industries like pharmaceuticals, food and beverage, electronics, and textiles. Within these sophisticated machines, the oil demister plays a vital role. It effectively separates any minute oil droplets from the compressed air stream before it leaves the compressor.
Over time, however, the demister element can become saturated, reducing its efficiency. This can lead to decreased air quality and potential contamination of your downstream processes. Therefore, regular replacement of the demister element and its associated seals is absolutely necessary. This kit provides the vital components for engineers to keep their equipment running smoothly. It ensures your oil-free compressed air remains truly oil-free, protecting your products and processes from harmful contamination.

Real User Experience
"In our electronics manufacturing facility, absolutely oil-free compressed air is a non-negotiable requirement for our sensitive processes. We rely heavily on our Atlas Copco ZH37 compressors. When it came time for routine maintenance, we opted for the genuine Atlas Copco 2906904500 OIL DEMISTER SERV.KIT from BOAO. The quality of the demister element and the O-rings was immediately apparent. The installation was straightforward, and everything fit perfectly. Since the replacement, our air quality checks consistently confirm zero oil aerosols, ensuring our products remain untainted. We've also observed a slight but noticeable improvement in compressor efficiency, leading to a 5% reduction in energy consumption for the same output. This kit provides invaluable peace of mind, knowing our critical processes are fully protected."

Installation Steps
Replacing the oil demister service kit is a critical maintenance task. It requires technical expertise and strict adherence to safety protocols. While these steps offer a general guide, always refer to your specific Atlas Copco oil-free compressor’s operation and maintenance manual for precise, model-specific instructions and safety warnings. Professional installation by a qualified technician is highly recommended.
- Ensure Safety First: Begin by completely shutting down the air compressor system. Isolate it from all power sources and ensure all stored pressure is fully relieved before starting any work. Apply lockout/tagout procedures to prevent any accidental startup.
- Locate the Oil Demister Housing: Identify the oil demister housing. It is typically located within the air/oil separation system of your oil-free compressor.
- Prepare for Disassembly: Place a clean cloth or container to catch any residual oil or condensate. Ensure you have the appropriate tools for disassembling the demister housing.
- Disassemble the Housing: Carefully unbolt or unscrew the housing that contains the demister element and O-rings. Be mindful of any remaining pressure or fluid.
- Remove Old Components: Extract the old DEMISTER ELEMENT and the old O-RINGS from the housing. Inspect the housing cavity for any wear, damage, or debris. Clean the cavity thoroughly to ensure a proper seal for the new components.
- Install New Kit Components: Carefully place the new DEMISTER ELEMENT and the new O-RINGS from the 2906904500 kit into the cleaned housing. Ensure each part is oriented correctly and seated properly according to your compressor's manual. Lubricate O-rings lightly with clean compressor oil if specified.
- Reassemble the Housing: Securely reassemble the demister housing. Ensure all bolts or screws are tightened evenly and to the manufacturer's specified torque. Do not overtighten, as this can damage the housing or components.
- System Re-pressurization and Leak Test: Slowly re-pressurize the compressor system. Once operational pressure is reached, carefully check for any air or oil leaks around the reassembled demister housing using a leak detection solution.
- Functionality Verification: Monitor the compressor's performance, paying close attention to air quality and any pressure drop across the demister. Confirm that the system is operating efficiently and producing clean, oil-free air.
